i have a century 2 speed 2 hp 1081 pool and spa motor now, sp1615z2msc I know 1 1/2 hp pump is enough for my pool will this motor replace mine size wise
Hi, Gary. The correct replacement motor is the Century B977 Motor. This 1/2 hp motor may not provide enough water flow to turn over the water depending on your pools feet of head.
I need a 1hp motor for a jacuzzi magnum 1000 . My pump has a lock ring on it.
Hi, Dom. Based on the info I've gathered the Magnum 1000 uses a 50Hz motor which we do not sell. If that's not the case and it uses a 60Hz motor the UST1102 Motor would be the correct replacement. In order to confirm we'll need the motor info.
Is there a VFD you can recommend that can be wired to this 0.5hp motor?
Unfortunately, I am not aware of one for that low of horsepower. Not saying that they do not go lower, but the lowest I have seen them go is 1HP.
my timer got stuck on the clip and the motor kept trying to go off but couldn't so, did I burn out the motor or the bearing. It still hums when I turn the power on after I let it cool off but want pump water to the filter.
It is possible that the motor has burned out. You will need to remove the motor from the pump housing and test to see if the motor is still turning the impeller. If yes, try is out when connected to the pump to see if it will primp and circulate water. If it is not turning, it is time to get a new motor.
I'm trying to replace the motor on my pool pump but all these numbers and abbreviations on the motor label are really confusing me. What do they mean?
Replacing a pool pump motor is not as difficult as it seems. You can try looking here. If you need help figuring out what the information on your label means. If you are still having difficulty figuring it out you can call us at our toll free number or you can send us a photo of your motor label here.
I'm trying to find a replacement motor for my pool pump but my model number doesn't match what you have listed as the model number. My model number begins with a C48 and yours begins with an SP. Please help.
What we have listed on our chart pages is the pump model number. The model number you have will just identify the motor. If you look on the plastic housing on the pump there should be a sticker which will have the pump model number. You can usually find this by the discharge port on the pump. Once you locate it you can choose the correct replacement motor. Be certain to change the shaft seal and gaskets as needed. You can use our >How to guide if you need help.
Why should I purchase a Tune Up Kit?
A Tune Up Kit includes all of the essential replacement seals and gaskets for the pump. The seals and gaskets should be replaced when installing a new motor on your pump. New seals will prevent the pump from leaking water or losing the prime. A Tune Up Kit will protect your motor and ensure that the pump is working efficiently.
Why do I need to purchase a new shaft seal?
We strongly recommend replacing the shaft seal. The purpose of a shaft seal is to prevent water from running down the shaft of the motor and into the motor housing. Water will damage the bearings and cause the motor to fail. A new shaft seal should be installed whenever a motor is replaced. The motor manufacturer can deny the warranty if the motor fails to due to water damage from a faulty shaft seal. To find your shaft seal you will need to visit our Pool Pump Parts Page or the Spa Pump Parts Page and select your make and model.
What is Service Factor?
Service Factor(SF) is a multiplier that when multiplied by the horsepower of the motor indicates the total permissible horsepower loading that may be carried when the motor is operating at rated voltage and frequency. The most important thing to remember when replacing a motor is that the replacement motor's horsepower times its service factor must be equal to or greater than the original motor's horsepower times its service factor. The Service Factor rating can be found on the motor label. See Step 4 of our How to Read a Pool Motor Label guide.

Pros: well packed for shipping

I checked w/pool supply places this was the cheapest and the "no Shipping charge" is what sold me. Arrived well packed. Works perfect. When I called on phone for ordering help to make sure I was ordering the correct replacement motor, Sharon helped me with consideration, kindness and patience. Excellent customer service.
